Unit 10 PreAssessment

Front

What is a solution in the context of a coordinate plane?

Back

A solution is a point (x, y) that satisfies the equation of a line or curve on the coordinate plane.

Front

How do you find the y-intercept of a linear equation?

Back

The y-intercept is found by setting x = 0 in the equation and solving for y.

Front

What does the inequality 6x + 2 < 14 represent?

Back

It represents a range of x values that satisfy the condition, specifically x < 1.

Front

What are x-intercepts?

Back

X-intercepts are points where the graph of a function crosses the x-axis, meaning y = 0.

Front

How do you determine the x-intercepts of a quadratic function?

Back

Set the function equal to zero and solve for x.

Front

What is the significance of the y-intercept in a linear function?

Back

The y-intercept indicates the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What is the general form of a linear equation?

Back

The general form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you graph a linear equation?

Back

To graph a linear equation, identify the y-intercept and use the slope to find another point.

Front

What does it mean for a point to be a solution to an inequality?

Back

A point is a solution to an inequality if it makes the inequality true when substituted into the equation.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run between two points.
